Dans cet article, nous étudions les techniques de macro/micro diversité pour l'acquisition de code d'un signal à spectre étalé en séquence directe dans un système de communication par paquets en intérieur. Dans le système présenté, la station de base dispose de plusieurs ports radio dotés chacun d'un groupe d'antennes, et le terminal dispose également de plusieurs antennes. Les performances dans la liaison montante de ce système sont analysées sous ombrage lognormal et évanouissement plat de Rayleigh. Les résultats numériques montrent de grandes améliorations des performances grâce aux techniques de diversité proposées. En outre, il est précisé que le temps d'acquisition moyen, qui est souvent utilisé comme mesure des performances, n'est pas adapté aux systèmes radio par paquets car il sous-estime la longueur de préambule nécessaire pour l'acquisition initiale du code.

Abstract: In this paper, we study macro/micro diversity techniques for code acquisition of a direct-sequence spread-spectrum signal in an indoor packet communication system. In the system discussed, the base station has several radio ports each with a cluster of antennas, and the terminal also has multiple antennas. The performance in the uplink of this system is analyzed under Lognormal shadowing and flat Rayleigh fading. The numerical results show great performance improvements by proposed diversity techniques. In addition, it is clarified that the mean acquisition time, which is often used as the measure of performance, is not suitable for packet radio systems as it underestimates the necessary preamble length for initial code acquisition.
